Is there anyone out there that is plowing snows (up North) with a pusher blade on a 33-35 HP Tractor? a 8 footer or 10 footer?

You would not be able to go that big if your expecting to push with wet snow. My land loard used a 10ft with his 70-75 hp back hoe and he didn't want to go bigger. I had a 63inch blade my kubota zero turn and dryer snow I could push 2ft no issues, but wet snow your talking foot max. That was a 26hp diesel. I would think 6-7 foot would be about your max in a box blade unless your never planning on pushing more than 3 inches of snow. My issues was weight on my zero turn. About 1800 lbs, but power would be your issue. Also box blades that big with snow you would never be able to lift it. A 8ft blizzed power plow is like 1100 lbs.

We have a 3320 JD 4 WD and a 5093 4 WD, I am thinking that the 10 foot should be no problem for the 93 HP JD, but it sounds way too big for the 33 HP.

I rented a 3320E for a couple of days. No way is going to push that much. It struggles to get up to top speed let alone push a 10ft blade. On the 93hp you might be able to go 12ft or 15ft. I know they put 15ft on 100hp skid steers. I would say 7ft max on the 3320 and you need to add a rear weight of some sort and maybe chains. Maybe a 10ft power plow would be the best option. If it gets to deep you can go to 8ft striaght blade mode.
